T o all whom t may concern Be it known that I, HEINRICH CrnusriAAN FERRON, a subject of the Queen of the Netherlands, residing at Prinsengracht 911, Amsterdam, in the Kingdom of the Netherlands7 have invented certain new and useful Improvements in Metallic Roofing and the Like, of which .the following is a specication.

This invention relates to nailless metallic rooiings and the like of the kind in which metallic plates are attached by means of bent tongues integral therewith to allotted one-piece metallic purlins.

In my United States Letters Patent No. 780,946 there is described a rooting of the kind referred to, and in my United States Letters Patent No. 935,479 there is described a slotted one-piece metallic purlin for use in such roofngs.

The present invention has for its object to overcome certain ofthe disadvantages possessed by these previous arrangements and to this end it provides an improved construction of purlin and also of plate or tile whereby a stronger and more economical structure results, which is weatherproof and which is easy to repair.

According to the invention the roofing or the like comprises one-piece slotted-metallic purlins bent in such a way as to receive and accommodate the upper ends of metallic roofing plates, each of which plates is provided along its upper edge with an u standing from which proj ect. retaining tongues adapted to take into the slots in said purlins.

The purlin, which is adapted to be secured to the rafters, is formed from a single strip of metal bent upon itself with a narrow distance piece separating the two overlying walls; equidistant slots being pierced along the line of junction of the upper edge of said distance piece with the upper overlying wall. The height of the distance piece is just suiicient to permit of the insertion of the upper edge of the metall-ic plate into the channel formed by the bent strip.

The metallic plate or tile, which may for example be rectangular in Shape` is formed with a corrugation along each side edge and with an upstanding flange along the upper edge of the same height as the corrugations. Integral with this flange are one or more, preferably two, projecting tongues set apart une B. B. F

yis

' with apertures l and along transverse flange or weather stripy purlin below that with whic the tongues age the next.

at the upper edge of the plate engage. The

purlins and plates may be applied either to roofs or to walls of buildings.

The invention is illustrated in the accompanying drawings in which- Figure l shows a blank purlin after having been stamped out and before having been bent to shape. Fig. 2 is a ers ect-ive front View of the same purlin a ter' aving been bent to shape. Fig. 3 is a section on lineA. A. Fig. 2. Fig. 4 is a perspective view of one of the metallic plates or tiles. Fig. 5 is a front elevation of a portion of roong constructed f vthe purlins and tiles of this invention, and Fig. 6 is a section on 1g. 5. Referring to F igs.I 1, 2 and 3, each urlin composed of a long narrow strip o sheet iron, sheet steel or other suitable metal, which when in blank form is stamped along one edge at suitable distances apart the opposite edge with notches 2 disposed opposite to said apertures 1. At the same time the strip has stamped out of it a row of slots 3 which are located in alinement at equal distances apart and parallel wit-h the notched edge of the strip. After being treated thus the strip is placed'in a suitable bending machine and is bent upon itself to the section shown in Fi 3, in which 4 is the lower member .in whic the apertures 1 are situated, said apertures serving for the passage of nails whereby to attach the strip to the wooden rafters of the structure. 5 is a distance iece or back member bent up at right ang es from the lower member 4; and 6 1s the upper member of the strip which is bent forwardly at right angles from the back member 5, said upper member 6 having the notches 2 along its edge at points above the nail apertures 1 in order` to permit the nails to be reached by a hammer. The purlin is thus formed of a length of metal of channel section whereof the lower member 4 bears on the wooden or other rafters. The equidistantly spaced slots 3 are disposed along or just below the line on which the member 6 is bent from the back or distance piece 5. 7 is a rectangular plate or tile also of sheet iron, steel or other suitable material which is stamped to shape and is provided as in my previous construction with corrugation alon each side edge. The portion of the material intervening between the two corrugations may be plane or it may be embossed as desired; and along its upper edge said plane portion is formed with an integral upstanding flange or weather strip 8 extending above the plane portion 7 of the tile for a dist-ance equal to theheight of the corrugations. The iange or weather strip of .tongues 9, 9, spaced the same distance apart'as the slots 3 in the purlin, and the lower vedge of the tile is formed with an extension or tongue 10.

In- Fig. 6, 11 is` one of the wooden rafters of a portion ofl a roof of a building and across these rafters the purlins are affixed by their lower members 4 being nailed thereto. The plates or tiles 7 are inserted in place by passing the tongues 9, 9, through the slots 3 and bending said tongues downwardly of the back or distance pieces 5. The lower edge of each plate or tile rests on the member 6 of .the next purlin below, varound which mem- 'berl the extension l0 is bent as seen clearly in Fig. .6. In this manner all'the tiles are axed to the purlins, either with the marginal corrugations in alinement downwardly of the structure or with said corrugations 1n staggered formation as shown in Fig. 5. It

will be noticed that the distance separating' the two members 4 and 6 of each strip 1s just sufficient to accommodate the 'upst-andlng flanges 8 of the tiles and that these flanges or weather strips 8 prevent access.

beneath the roof of any rain, dust or snow which may be driven up by the wind. Similarly the eXtenslons 10 asin the previous constructions, prevent ingress of rain along the lower e'dges of the tiles.

Furthermore these flanges 8 and the bent extensions l0 serveas bearing surfaces against the purlins to secure theY plates or tiles against lateral displacement by the wind, the flanges 8 resting firmly against the back or distance piece 5 of each purlin. Ample ventilation is secured byway of the laterally disposed corrugations. In this form of roofing or the like the plates or tiles interlock withthe purlins so as to form a considerably stronger structure than heretofore, and the shape of the plates orY tiles is such that considerably less material is required in their manufacture than Awas previously the case. The plates 0r tiles and purlins may serve equally well for the side walls of buildings as for the roofs, and said plates or tiles may be ornamented in any desired manner and may be protected from atmospheric changes or from reflecting the suns rays by means of any desired coating or composition.

8 is provided integrally with a pail" With the above described construction many facilities are-.aorded in the construction of a building. For instance ordinary ridging having joints may be entirely dispensed with, and insteadtwo purlins may ybe placed back to back at the apex of the roof and a continuous strip of lead may be folded over same, so that its edges take under the oppositely disposed upper members of the two purlins. Again, the 'structure is very simple to repair, for a single tile may be removed from within with great facility by simply straightening the tongues 9, 9, and allowing t-he damaged plate ortile to drop out, after which a fresh'ftile may be slid into place. By placing the slots 8 in the purlins at equal distances apart no difficulty is experienced in arranging the plates or tiles in staggered 'rows or otherwise as desired.

What I claim -iszl 1. In a metallic roong, the combination f upper andlower purlins of channel secion arranged in spaced, parallel relation and aving their lower side walls disposed against the roof rafters; and a row of metal tiles interposed between said purlins and housed atl their upper ends in the space between the side walls of' the upper purlin, each tile being formed It itsupper end Wit an upstanding weather-ltripping flange having a tongue engaged with the connecting 'wall of said upper purlin, and being formed at its lower end with an extension removably bent over the upper'l side Wall of the vlower purlin.

2. In a metallic roofing, the combination of upper and lower purlins `of channel section arranged in spaced, parallel relation and having their lower side walls disposed' yslots at the junction of its upper side wall and connecting wall; and a row of metal tiles interposed between said 'purlins and ihoused at their upper ends in the space between the side walls of said upper purlin, each tile being formed at its upper end with an upstanding weather-stripping fiange having its upper edge provided with a tongue which is inserted through the adjacent slot and bent downward against-` the connecting wall of the said upper purlin, and being formed at its lower end with an extension which is bent over the -upper side wall of the lower purlin and inwardly against the under surface of such wall.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
